RE: CMP Zero 80
If you are just getting started on this CMP Zero do yourself a big favor and reinforce the firewall area with fiberglass and extra plywood. I am going to be reinforcing mine with extra fiberglass. I will be using the thin plywood ring that mounts as a template and making one out of 1/2 plywood. This bird needs a lot of nose weight even if you use a heavy gas engine so you might as well us the extra weight that is needed to reinforce the firewall. You'll be happier in the long run believe me.
The cowl my friend is going to be making for me is going to be heaver then the original one and will hold up to a nose over landing. I lost my original one that why and been looking for one for over a year know.

RE: CMP Zero 80
Finally I can post the pictures. So here are the promised pictures of the cowl.
Chris are the dimensions same as yours?
Last weekend I had to walk the dog and the weather was beutiful for the flying with my small Zero on the play ground behind my house. So I joined pleasent thing with the necessary thing.
My friend was very helpful, so I had two planes.

I have a World Models Zero and the retract mounts were junk. I totally redid the mounts this way and it has held up for 11 years and many flights. Just flew it again the other day. More photos in my gallery. Paul

80" Wingspan BME 44 engine. There is a video of it flying as well as a nice Heli cam of our field on our website - spacecityrc.com check it out! PS. it is mistakenly labeled as a CMP Zero. Paul

Prekin ,
I think your cowl measurements are close to mine . not exact but close enough . They could have been from different plugs or suppliers . I don't think there is enough difference to be concerned with though.

Pics,
You really can't see much of the engine because the spinner fills up most of the cowl opening . On my current Zero I used a dummy radial that I got from Nick Ziroli which I had laying around . I wont waste my time fitting a dummy radial on the next one since you cant see much of it anyhow.

If you don't want to mess with a dummy engine, I made a couple with this picture and print it to size. Glue it to a paper plate and secure with gorilla glue to the cowling. Costs nothing and lasts a long time if you go over it with thinned 30 min epoxy. Paul

RE: CMP Zero 80
Thank you guys,
your pictures are perfect.
Chris, I know, that I won´t be able see the engine because of the spinner. I would like to set it on my Zero after the maiden flight. I don´t want to risk a destruction if the maiden flight wouldn´t be good.

RE: CMP Zero 80
Lots of talk about the Zero cowl here. Has anyone compared the CMP cowl to the Yellow Aircraft cowl. The airplanes are a very similar size overall. I own a completed Yellow Zero and a CMP kit but the kit is stored away and access isn't easy. At any rate, the YA cowl is very well made and available. Lots of nose weight in that YA plane but it flies great.

RE: CMP Zero 80
After getting the measurements & pictures of the cowl from you guys my friend said it looks like the cowl tappers some from the firewall to the nose. So I bit the bullet and ordered another CMP 80" Zero. It arrived Friday and now we have a good cowl to use as a mold to make a much stronger cowl. I'll post some pic's of the new cowl once Paul has them finished. We are hoping to have two CMP Zeros after this once we are done.
I will take a look at the YA cowl and compare it to the CMP cowl if I can.
